LUBRICATING DEVICE.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed October 9, 1915. Serial No. 54,958.

To all whom it may concern:

Be it known that I, VJILLIAM'G. BROOKS, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Lubricating Devices,

of which the following is a specification.

My invention relates to lubricating devices, and particularly to the oil and waste lubrication of bearing housings for dynamoelectric machines.

One object of my invention is to provide a lubricating device having oil and waste chambers that are separated by a partition which permits of a free interchange of oil at all levels but which maintains the waste in its proper chamber.

Another object of my invention is to provide a lubricating device having a longitudinally-slit partition for separating the oil from the waste chamber, which will greatly facilitate the removal of waste by the use of a waste hook.

In lubricating devices of usual construction having the oil chamber separate from the waste chamber, the opening between the chambers for the passage of oil is at the bottom of the oil chamber. Thus, any dirt collecting in the bottom of the chambers will tend to clog the opening and prevent the free passage of oil. In such lubricating devices, moreover, when it is necessary to remove the waste, a hook must be inserted into the waste from the top of the waste chamber, making it diflicult to remove waste at the bottom of the chamber.

In a lubricating device constructed in accordance with my invention, however, a slit is placed in the partition between the oil and waste chambers, thus providing a passage way for the oil to flow from one chamber to the other should the opening at the bottom become clogged, and a means whereby a hook may be inserted into the bottom of the waste chamber.

It is the practice with many railway companies to use an oil during the summer months that congeals at a comparatively high temperature. Thus, at each sudden lowering of the temperature, the oil will tend to congeal to some extent, and, in a lubricating device of the usual construction, it will be unable to filter up through the waste to the bearing. However, with a lubricating device constructed in accordance with my invention, the bearing may be saved, for should the oil congeal and clog the opening at the bottom of the oil chamber additional oil may be applied which will flow through the slot directly to the bearmg.

My invention is illustrated in the accompanylng drawing in which Figure l is a vlew, partially in section and partially in end elevation, of a split-frame railway motor constructed in accordance with my invention, and Fig. 2 is a sectional view of the oil and waste chambers taken on the line II-II of Fig. 1.

Referring to the drawing, a split-frame rallway motor 1, mounted on an aXle 2 for a set of wheels 3 (one only being illustrated), is provided with an armature bearlng housing 4 mounted upon an armature shaft 5. The armature bearing housing 4 embodies an oil filling and gaging chamber 6, a waste chamber 7 which is filled with waste 8, and an armature bearing 9 having an opening 10 into the waste chamber. The 011 and waste chambers are separated by a partition 11 having an opening 12 and a longitudinal slit 13 and are provided with a single cover 14.

The partition 11, which separates the oil and waste chambers, may be an integral part of the housing casting, in which case the slit 13 and opening 12 are formed by a core. However, such a structure is not material to my invention, as the partition 11 and the housing casting may be separate parts joined in any convenient manner. It may be noted that the lower edges of the partition 11 are chamfered to permit a free movement of the packing hook when removing waste.

The function and operation of the lubrieating device herein described may be as follows: The waste chamber 7 is supplied with waste 8 which is pressed into contact with the motor shaft 5 through the opening 10 in the bearing 9, thus permitting oil to be supplied to the bearing whenever the oil chamber 6 contains oil. The oil, supplied to the oil chamber 6, will at once flow into the chamber 7 filled with waste, and, by capillary attraction, filter through the waste to the bearing 9, leaving any dirt that it may contain at the bottom of the oil chamber. Thus, in time, suificient dirt may accumulate to fill the opening 12 at the bottom of 1M the oil chamber and, if this were the only means for supplying oil to the waste, it might prevent any oil from reaching the bearing. However, the slit 13 in the parti- 5 tion separating the two chambers provides a second path for the flow of oil. When the waste has been in use for some time and it is desired to renew the same, the slit 13 may be conveniently used as an opening for inserting a hook for removing the waste.

Various modifications in the structural details of the lubricating device may be efi'ected without departing from the spirit -and scope of my invention, and I desire, 15 therefore, that only such limitations shall be imposed as are indicated in the appended claims.

I claim as my invention: 1. In a lubricating device, a member having waste and oil chambers, and a partition between the chambers having a longitudinal slit therein for admitting a waste-1emoving hook.

2. In a lubricating device, a housing member having oil and waste chambers, and a wall between said chambers having a vertically-extending slit with diverging lower edges to facilitate theinsertion of a waste-removing hook.

0 3. Ina lubricating device, a member having waste'a-ndoil'cha-Inbers, and a-wall between the chambers having an opening extendingfrom the top to the bottom of said Wall,- said opening permitting. of a free in terchange ofzoilzat all levels.

4. Inalubricating device, a memberhav- 'ing waste and oil chambers, and a wall between said chambers having an opening at the base thereof and a vertically-extending slit, the corners of said slit wallbeing chamfered where the two openings meet.

5. In a lubricating device, a member hav ing an oil filling and gaging chamber, a waste-containing chamber, and a wall between the two chambers having a longitudinal slit therein and an aperture intercommunicating with said chambers at the base of said wall.

6. In a lubricating device, the combination with a member, having a chamber for containing oil, a chamber for containing waste, and a vertically-split wall between the two chambers having apassageway intercommunicating with said chambers at the base of said wall, said vertical slit diverging to form said passageway to facilitate the insertion of a waste-changing hook.

7. In a railway-motor frame, the combination with a housing member, of a partition dividing the housing member into a chamber for containing oil and a chamber for containing waste, said partition having a longitudinal slit for admitting a Waste-removing hook, and an opening at the bottom between the two chambers, a rotatable member, and a bearing having an opening whereby oil may be applied to the rotatable member.

In testimony whereof, I have hereunto subscribed my name this 27th day of" Sep: tember, 1915.
